This is way off topic, but I've been racking my brain (and The Google) and can't figure out the names or names of some vintage cartoons that feature characters from different books interacting in a library or on bookshelves - anybody know what I'm talking about? Thanks.

Great list and I've been able to find some of them on YouTube. I noticed Clampett lifted the cuckoo clock (and a bunch of other bits) right out of Have You Got Any Castles? (http://www.youtube.com/watch?v=xEF-yP9EvZg).
